Imagine Rajesh, a small hardware shop owner in Lucknow. He hired a helper and paid him over the limit, so he now needs to deduct TDS. He searches “tan application in 2026” and feels lost. The single old Form 49B is gone. 

The government has introduced new TAN forms in India– Form 134 for government entities and Form 135 for everyone else. Which one should he use? Where to apply? What documents are needed? This simple, step-by-step guide answers all your questions in easy language. By the end, you’ll know exactly how to complete your tan application in 2026 without mistakes.

PAN is now mandatory for all non-government applicants. These new TAN forms in India make the process simpler, reduce errors, and improve tax compliance in India.

How to Choose Between Form 134 and 135

• If you are a government office or department, → Use Form 134. 
• If you are a private business, shop owner, individual, company, or LLP → Use Form 135. Choosing the wrong form can lead to rejection.

TAN vs PAN: Simple Difference Everyone Should Know

TAN is your special ID for TDS/TCS duties. Without it, filing returns or issuing certificates becomes difficult.

Who Needs TAN in 2026? (And Who is Exempt?)

You need TAN if you must deduct or collect tax at source (TDS/TCS) and file statements or issue certificates.

You Need TAN If:

• You pay the salary and deduct TDS.
• You pay rent, contractor fees, professional fees, interest, etc., above the threshold.
• You run a company, firm, LLP, shop, or business that regularly deducts TDS/TCS.

Exemptions (No TAN needed):

• Resident individuals and HUFs deducting TDS on property purchase from resident sellers (use PAN instead under Section 194-IA).
• From October 1, 2026: Resident individuals and HUFs buying immovable property from Non-Resident Indians (NRIs) can use PAN-based challan (no TAN required).
• Certain low-value or one-time deductions (e.g., under Sections 194-IB for rent by individuals/HUFs, 194M, etc.) allow PAN in place of TAN.

These exemptions reduce the burden on small taxpayers while maintaining tax compliance in India. If you deduct TDS regularly as a business, get a TAN to stay safe and avoid penalties.
